Hey Charlotte!
Are you just looking to append new information in new rows? If so, I would remove the 'update cell' skill/action. It looks like it's consistently Overwriting F1.
If you're looking to update full rows, I would use the 'Update Row' action/skill, which you already have. You can still delete the 'Update Cell' action/skill.
I see you have a bunch of agents with a lot of skills within them. I would highly suggest being more specific with your skills/actions added to your Agents!
Please let me know if that helps
